Recall on Coolant caps

In my post above, I meant to say that pressure as well as antifreeze work to raise boiling point.

Aside from the temp/pressure and boiling point discussion, this problem reminds me of an old BMW I formerly owned (84 533i) that used to overheat frequently. After replacing all the obvious cooling system items, which did nothing, it turned out that the cylinder head was cracked and allowing exhaust gasses to enter the cooling system, thereby causing an air break and boil over.

Any chance this Boxster has a cracked cylinder head causing a similar problem?

Its possible but the boiling thing does not hppen all the time. Once in a while. Is it bad when it boils. if it is a craked head that is $4000 or more to fix Can I live with it if it only happens once in a while?

I bought my coolant cap from Suncoast about 8 month ago (before they released the 03 version). I called Suncoast and found out that if i take the bad coolant cap that i have to ANY Porsche dealer they will replace it free of charge as long as i have the invoice. They also told me that if i didn't have the invoice they would email me one. All original Porsche Parts have 2 years unlimited kilometer warranty on them and these warranties are honored at any Pporsche dealer.

I was very happy about. I did that on Saturday and it did work.
